Well on the the former, Gaming Intel has not been wrong once and got all the direct dates in recent history right. So i don't doubt them.
As for the later,
I don't buy Erderick when all insiders were wrong, and I think the arguments made against him further burying that nonsense. I don't think square would do it. Hell I don't even think square has a rep for DLC atm.
And if we go by Brave's stats and the microsoft love lately, then I think the bear is likely. Steve is shut down. Chief can still happen, but I think Banjo's coming and I'm not even a huge banjo fan. Never played his games.
